WAYNE S. SEARLES, OF PROVIDENCE, RHODE ISLAND, ASSIGNOR TO UNIVERSAL OPTICAL CORPORATION, OF PROVIDENCE, RHODE ISLAND, A CORPORATION OF RHODE ISLAND.

FINGERJIECE MOUNTING FOR EYEGLASSES.

To all whom it may concern:

Be it known that I, WAYNE S. SEARLES, a citizen of the United States, and a resident of Providence, in the county of Providence,

State of Rhode Island, have invented certain Improvements in Finger-Piece Mountings for Eyeglasses, of which the following is a specification.

One object of my invention is to provide .a simple, substantial and relatively inexpensive mounting for the so-called finger pieces forming part of or attached to the guards of eye-glasses, which while being of such a construction that none f'itsparts shall become unscrewed or loosened under conditions of use, shall permit of the con-. venient removal of said guards or their' associated parts.

I further desire to so arrange the nose it to become loosened and ultimately lost.

These objects and other advantageous. ends I secure as hereinafter set-forth, ref

erence being had to the accompanying draw- 1ngs, 1n wh1c-h:

vention as applied thereto; Fig. 2, is a plan of the parts shown in Fig. 1; Fig. 3, is al side elevation of part of the eye glass frame shown in Fig. 1, but with the finger piece. and spring removed; Figs. 4 and 5 are two plan views of the spring in its unformed.

ture. A nut 6 is mounted on the threaded upper end of said stud on which is also loosely carried a guard whose arm is indicated at 7. This latter is extended to provide the finger piece 8. In order to cause the guard to firmly engage the nose of the wearer of the glasses, a spring is likewise mounted on the stud 5 as indicated. Said spring consists of a flat strip 9 of spring material having a hook 10 at one end and in the present instance an enlarged perforated portion 11 at the opposite end; it

being noted that said portion extends practically at right'angles to the general line of the strip and'ha's'a projecting arm 12. In

forming this spring to serve the purpose for which t is designed, the part 9 is bent at right angles on the dotted line indicated at 13, so as to lie in a plane at right angles to theplane of the part 11, and is thereafter coiled to form a spiral spring surrounding the stud which projects through the perforation in the part 11.

' In mounting the spring on the eye glass frame it will be noted that the hooked end 10 thereof is caused to engage the arm 7 of the nose guard, while the projection 11 lies lmmediately under the nut 6 so that the 1 arm 12 engages the strap 3. \Vith this ar- Figure 1, is a side elevation of a portion of an eye-glass frame, illustrating my 1n rangement of parts, the movement of the finger piece 8 toward the bridge, and of the guard with its arm 7 away from the same,

'is resisted by the spring which tends to retions of the spring upon their post 5, can by no possibility affect the nut 6 or tend to turn it on said post to cause it to become unscrewed, and as is obvious, there is no possibility of the stud or post becoming loosened in the part 4 of the frame in which it is mounted, since, as noted, it is As an addiwith a number of marginal projections 16 any one of which maybe turned up to enter one of said recesses to rigidly and positively hold the nut from rotating after the parts o f 't-hedevice have been assembled. As is obvious, these 'pi' ojections and the recesses of the nut maybe omitted without departing from my invention. By this particular construction I have obviated a most serious objection to the use of spring actuated nose guards of the removable type, for much trouble has hitherto been experienced owing to the loosening of the spring-supporting screw'under conditions of use. With my invention, when it is desired to remove the spring, the nut may be very conveniently and quickly taken from the stud 5 as may also the nose guaid;-the projections 16, if used, being bent down to permit the nut being turned. At the same time, after the parts have again been assembled and the nut screwed up to the desired point, there is nothing tending to cause it to become loosened even under the most severe conditions found in practice.

It is obvious that under certain conditions, the nut may be omitted and the upper end of the stud formed as indicated at 5 in Fig. 8, with a transverse notch 14. With this construction the spring and nose guard are mounted on the stud as before and the part 11 of the spring so far enters the notch as to prevent said parts being removed or becoming displaced as long as the hooked endlO remains in en gement with the nose guard. If desired, may, under certain conditions, form the spring with a straight lateral extension 11 as shown in Fig. 6. In this case the stud or 0st extends through t-hecenter of the coile spring, and the part 11 forms a straight arm-for engaging the strap 3.

It will be understood that while I- have illustrated but one end of the'frameof a pair of eye glasses, the opposite end is of a. similar formation, and like that shown is provided with lens holding devices an a guard mounting identical in construction with those shown. If desired I may, under certain conditions, form the spring from wire of circular section instead of from flat strip material as heretofore described, without departing from my invention.

I claim 1. An eye' lass frame having at each end a device for t 1e attachment of a lens; a post permanently mounted in said frame; a noseguard; a flat strip wound around the post to form a spring; said spring and guard both being mounted on the post and the spring being-hooked to the guard; with a nut on the post for confining the sprin and guard in position, and means for 1101 ing immovable the part of the spring adjacent the nut when the guard is moved. I,

2. An eye lass frame having at .each end a device for t eattachment of alens; a post permanently mounted in said'frame' a noseard and-a 'sprin for actuating -t or same oth mountedon t e post; "means for holding immovable a portion of saidspring adjacent the free end of the post and lying in a plane at right angles to the plane of the main portion of the spring; with means for holding said parts on the post.

3. An eye glass frame having at each end a device for the reception of a lens; a post permanently mounted on said frame; a nut on the post; a nose guard and a spring both mounted on the post, said spring being connected to act on the nose guard with means for holding immovable a portion of the spring adjacent the nut when the nose guard is moved on the post.

4. The combination of an eye glass frame having at each end means for the attachment of a lens including a strap; a post permanently mounted on said frame adjacent said strap; a nut removably mounted on the post; a nose guard on the post having a finger iece; and a spring having one end operative on the nose guard structure and its opposite end in engagement with the strap; said spring being coiled around the post; with means for holding immovable a portion of the spring adjacent said nut when the nose guard is moved.

5. The combination of an eye glass frame having at each end means for the attachment of a lens and rovided with a strap; a post permanently hxed to said frame adjacent said strap; a nut for said post a nose guard loosely mounted on the post and provided with a finger iece; with a spring coiled on the post and iaving one end operative on the nose guard; the opposite end of said spring being perforated for the passage of the post and extending immediately adjacent the nut into engagement with the strap.

6. An eye glass frame having at each end means for the attachment of a lens; a post permanently mounted at each end of the frame; a nose guard and a spring for the same mounted on each post; with a nut threaded on the post and provided with recesses, said spring having projections formed to enter the recesses of the nut to prevent movement of the same.

7. The combination of an eyeglass frame having at each end means for the attachment of a lens and provided with a strap; a post on said frame adjacent each strap; nuts for said posts; 11. nose guard loosely mounted on each post and provided with a finger )iecc; with a spring coiled on each post anc having one end operative on the nose guard; the opposite end of said spring having an apertured flat portion for the passage of the post therethrough extending immediately adjacent the nut into engagement with the strap.
